'is as fol chain or carrier 'at the inlet end of the mawhich isadapted to lie over and engage the outer-edges of the cans as their'position is shifted between the guides, thereby preventingthem from becoming displaced.

The 0 eration of my improved machine lows: The cans are placed on the chine, one can'being placed in advance of each of the blocks 28,'resting on the upper edges ,oi'the channel-bar 8. At this time,

. the cans move iendwise. As they pass along betweenithe'.guides'9-l0 they are subjected to the heat ofith'e burners 18-19, which is.

then directed'i'gainst theside seams of the cans, thereby melting the solder contained h in thesame anduniting the parts. When the ran arrives at the flected ortion 17 of the guides 10, its forward end is deflected 'outward, such defiectioncontinuing as the can is, moved along, until the can. turns through an arc of ninety degrees, when it moves along s'idewise between the ends of the guides9-10, nearer the outlet end of the machine. During the turning opera-' tiOl'lt-h outer rear corner of the can moves inward across the concave faces of the blOCK 28, against which itrests; and as soon as the outer forward corner is deflected sufficiently,

it engages'the head 32 of the uide-pin 30,

passing partially under it, as s own in Fig.

' 1. By this means, the can is prevented from getting out of position during the turning operation, which is effected gradually, thereby minimizing the danger of displacement..

When the can is moved sidewise its ends are subjected to the heat of the biirners,tliereb melting the solder and completing the s'o dering; operation. While subjected to the line from end to end of the machine.

heat of the burners, the major portion of the body of the can is protected from the heat to a great extent by the edges 11 or 12 of the guides 910, "'espectively, as shown in Fig; 4. The lower surface of the can is also protected by the sides of the channel-bar, on which it rests, as also shown in Fig. 4.

When the can arrives at the outlet end of the machine, it may either be deposited in a receptacleplaced to receive it, or be removed by hand, as maybe desired.

It will be observed that the cans are conducted through the machine on a level bottom, the sideand end edges of the cans being each subjected to the heat of the burners, so that the solder is melted and the cans thereby soldered. The advantage of carrying the cans through on a leveli. 6., with their bottoms in substantially a llOIlAQIltfilPlilDG- is that the solder is kept from running when melted, as it would be apt to do if the cans were tilted to any considerable extent. It will also be observed that the guides by which the cans are turned upon the support-are deflected relatively to. the support as well as to the carrier,-said support and carrier extending in a substantially'straiggt s shown in Fig. 1, one of the channel-bars 8 is wider, at one end than at the other to provide a more extended support for "the cans when turned transversely to the line of movement of the carrier, but the channel- I bars together furnish a straight support for the cans. F

I have described my invention specificallyrbut I wish it to be understood that itis not restricted to the specific details of the construction described, except in so far as such details are particularly claimed. That which I claim as my invention and desire to secure by Letters Patent is,-
